Hi,
I have Ubuntu image downloaded from the site
"OrangePi_2G-IOT_Ubuntu_GSM_Package.rar "
I have tested the cellular modem using the picocom app, and also by writing python script (using pySerial commands).
when I send the AT command "AT+CSQ=?" to the cellular modem, it returns 20,99. first value varies between 17-25, but the second value is always 99 - that means that the RXQUAL is not detecatble.
I see that the modem is not registered to the network.
I did't succeed sending messages, strat calls etc.
I must admit I managed to send SMS and make a call only 2 times with the picocom app, but most of the time it fails and returns CME error:58 I think.
*tried with differe OrangePi 2G-IOT board - same probelm
* tried with different SIM - same probelm
* checked the SIM card volatge, it is 1.8V steady
* tried in different rooms - same probelm (I don't think it is signal power reception problem)
maybe it is a FW problem?
please help...
Dan
